In the figure given below, we have 3 lenses with the same focal length 10 cm, with the distance of separation between each pair of the lenses being 30 cm. An object placed 20 cm from the first lens on the left produces an image 10 cm from the right of the rightmost lens (See Figure). After the lens assembly was moved by x cm to left, without moving the object, the image was again seen at the same location. Find x.
x = 10 cmAccording to law's of reversibility when image work as object, object work as image.
x = 10 cm
According to law’s of reversibility when image work as object, object work as image.
